- The switch mechanism ,To ali 'whom t may concern.

it known that l, @Hmm-is il'. Kimm? o citizen of the lnited States, residing" :it Mil- Wziuliee, in the county ol Milwaukee and Stafi'e of llliiseonsin, have invented neuf and useful improvements in Elec-trio Switches, oi viiioli 'the following is a fullv clem', con- Oise, and exact description, reference being had to the accompanying drawing, forming :inert of this specification.

lili' invention relates to electric switches. lfi'wluis among its objects to provide :in inipiovcd electric switoli' .vhiehus especially stlixi'ited to use :is :i pendent switch, wherein, by the improved sii'angement and construe tion' oi' parts, the device may be inode to assume n; very compact and convenient form and muy be manufactured ut siniill expensea @they objects and advantages of my mirenv tion will hereinafter appear,

in 'oi-dei: to clearly ind fully disclose my invention, l have iliustisted one ox'm of the saine in the accompanying drawings. it is to be understood., however that the form. illustrated is susceptible of modification.

The bottom surface of this face is provided with a recess l() in which the switch mechanism is mounted, u pedestal 1l being provided at the center of the base to receive the spindle 5. As shown in Fig. 3, the con taots 'i' and 8 ai' carried in slightly deeper recesses on opposite sides of the buse and the Wall or flange l2 around the recess 1Q is provided with oppositely located slots or openings 13 through which the push buttons extend. The 'terminal connections for the switch mechanism :1re carried upon the 0pposits or upper face of the base in o shallow recess le, screws 15 und 16 extending from the contacts 7 and' 8 through to the top of the base and there being attached to 'terminal plates ll' und 18, carrying binding screws i9 und The base 9 is carried in a two-port ses 'J5 comprising :i shell 2l and :t cap 22. These two parts are arranged to be snapped lock them against longitudinal separation, suitable catches 23 being provided upon 'the upper end of the shell 2l and adopted to snap over an annuler flange 2e upon the ccp 22. ln order to prevent the relative iotntion of the two, pai-ts of the receptacle, the inteiiitting ends of the same :we matie polygonal asl shown in Fig. 2. IThe shell sidistanti:illyl cup shaped, being provided with s rounded bottom as shown. This member when united with :i cap 22, e ifoccptzicle of substantially acorn lili Ioinis shape. The switch mechanism is insulated from the1 sides oi: the member 21 by the beso f) und 'from the lowoil und of the same bu ineens .of en insulating!y lining 25 which held in position by downwardly extending sti'ucic-iu poi'tioirs 2li located substantially l "i the push buttons. The cap 22 of is insulated by means oi" un insulzi -g lining carried within the same by melius oit :in insulsting' bushing 28 which is pioviilod with :i flange 29 on its lower end adapted to hold the saine in position. As illustiziied in Fig. 1, vertically extending slots 30 zii-e piovided in the opposite sides of the port 2l to permit the switch mechanism io be slipped into position und to allow bhe iecipioouion o' the push buttons. As shown in lligf. 2, tno buse S) is provided with s pzsii oi' oppositely extending' lugs 8l lo- (waited ubovo ille push buttons und adopted to bc received in the upper ond of the slots 30.

lll@

lilla? It is to be Anoted that the edges of the slots are overturned as at 32 when they abut against the sides of the lugs 31.

In my improved construction the base is formed of a single piece of insulation which may be very readily and cheaply molded into exceedingly compact form.

. pending llange upon the same also serves to insulate the switch mechanism from the inclosing casing. Further, the terminals for the device are located in such a position that they are very readily accessible, since it is only necessary to remove the cap to gain access to the same. Further, these terminals are separated from the switch mechanismv sulating base transversely supported within said shell, said base having a substantially continuous depending peripheral flange affording a central recess, a snap switch mechanism mounted in said recess and insulated from said shell by said flange, said mechanism including a push ybutton operating member projecting through said flange and a contacter pivoted medially and movable in a plane substantially parallel to the plane of movement of said operating inember, and binding posts for said mechanism mounted upon the upper face of said base and beneath said cap.

2. In combination, a casing comprising a cup-shaped shell and a cap therefor, an insulating base within said shell having a depending peripheral lange forming a chamber, an insulating lining in said cap extending to said base and an insulating lining in said shell extending to said flange, and a snap switch mechanism mounted on said base and within said chamber.

In witness whereof, I have hereunto subscribed my name in the presence of 'two witnesses.
